An expansion tank is fastened to a support using a bracket with a U-shaped cross-section formed by a back and two sidewalls. The edges of the sidewalls each have a notch mating with a weld bead on the tank. Fasteners hold the back of the bracket to the support. First and second hose clamps pass through the sidewalls by the back to encircle the tank and clamp it to the edges of the sidewall when the hose clamps are tightened.

A joint restraint is provided for a curved pipe joint having a curved pipe section joining two adjacent pipe sections. The pipes are joined using tubular sleeves held by hose clamps to form fluid tight seals, with two clamps on each end of the curved pipe sections and two clamps on each proximal end of the adjacent pipe sections. An inner strap extends between and fastens to one of the clamps on each adjacent pipe section forming a chord of an arc. An outer strap extends along an outer periphery of the joined pipes and fastens to the other clamps on each adjacent pipe section. The straps are in a plane through a center of the flow path of the joined pipes.

A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.

Methods and systems for translating technology relevant addresses to user relevant addresses, and for translating less accurate location addresses to more accurate location addresses, are provided. According to a first embodiment, a method for displaying location information relating to a mobile device comprises using received signal information to identify a specific transmitter; determining a location of the identified transmitter; determining a Technology Relevant Address; calculating an Error Radius; translating the Technology Relevant Address to a User Relevant Address; recalculating the Error Radius; and displaying the User Relevant Address. According to a second embodiment, the method comprises using a first, less accurate technology, receiving signal information and using the received signal information to identify a specific transmitter; determining the location of the identified transmitter; calculating an Error Radius; determining if there is a More Accurate Technology Location Address within the Error Radius that is less than some time period old; translating the Less Accurate Technology Address to the More Accurate Technology Address; and displaying the User Relevant Address.

A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base. First and second, spaced apart, funnel shaped, diaphragm seals are connected to a first tubular passage or an adjustable length tubular extension. A cap for closing either tube has an inclined outer surface to form a beveled entrance to the passage in the concrete. An aerator box may be connected to the base. Hinged ends on the base allow the shape and length of support to be altered.

A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position. Flow through the testing device is allowed with the rotary valve closed and the tubular valve stem in an open position. With the rotary valve open, flow through the tubular valve stem is permitted when the tubular valve stem is in either the first or second position to provide multiple drain and fill options.
